9 Claims. (61.221 95),

This invention relates to automatic locking the rod Hi to a link 22which is connected to a means for dispensers and in particular relatesto pin 23 which is mounted on a bell crank lever 24 means whereby thedispensing nozzle may not. be pivoted on a pin 25. The lower arm ofthebell replaced on its hook until the operator haspercrank lever 24 isconnected by a pin 26 to a rod 5 formed a certain function, such ascausing the 21 which is connected by means of a pin 28 to a 5 mainoperating shaft of a registering machine lever 29 pivoted on a pin 30.The lever 29 is proto be operated. In ourapplication for Recording videdwith a pin 3| on which is hung a link 32 dispenser, Serial Number578,758, filed December provided with a slot 33 and a pin 34. [A pin'35is 3, 1931, we showed a recording dispenser which mounted on the frame36 of the registering mechwas adapted to pump any. predetermined quan-,anism' and extends through the slot 33 serving 10 tity of a fluid suchas gasoline, to record'the .asgaguidethereforl The pin 34 underliesalever number of gallons dispensed and the total price 31- pivoted on apin-carried bythe frame 36 to be paid therefor and after the gasolinewas and is provided with a latching finger 39. The issued the operatorwould press a button which lever 3! is also provided with a pin '49 onwhich would operate the main operating shaft of a is hnng arodlll whichis bifurcated at its lower 15 printing or registering mechanismwhich-would end andstraddles the shaft 6, Itis also provided print andissue a ticket andwould print a record with a pin 42 on which is'mounted a roller 43 to be retained within the machine. The object whichis normally seated in. a depression of a of the present invention is toadd a locking mechcam disk 45 secured to the shaft 6. I

6. Ina dispenser, a'lever, means controlled by the lever to dispense afluid", a hook on which said lever-is normally hung, a link connected tosaid hook, a latch normally holding the link against to 'be actuated bythe movement, means controlled by the lever whereby-said latch isdisplaced so as to permit said link to be actuated whensaid lever isoperated, and means to displacesaid been operated. s r

7. In a dispenser, a lever, meanscontrolled' by the lever to dispense afluid, a hook onjwhich said lever is normallyhung, a. plate, aslide'provided with a notch, means connecting said slide with said"hook, a latch,. saidj latch being normally engaged'in said notch andholding said hook, in ,1 l0 on, means operatively; connecting said latchand: H

a positionsuch that the lever may be hung therelever so that when saidlever is operated said latch will be displaced from the said notch, andmeans whereby when the latch is movedtowards plate the hook will bedisplaced so that'the lever cannot besuspendedthereom 8 In a dispenser,a discharge nozzle, a hook on which said discharge nozzle is normallysuspended, a slide provided withtwo notches, means connecting said slideand'hook, a-lever connected tosaid nozzle and adapted to control the newof liquid therefrom, a latch adapted to engage either of the notchesinsaid slide, means"con trolled by said lever when operated to removesaid latch from out of said notches, and means to thereupon move saidhook to a'position in which the nozzle cannot be hung thereon.

9. In a dispenser, adischarge nozzle, a hook on which said dischargenozzle, is normally suspended, a slide provided with two notches, meansconnecting said'slide and hook, a lever connected link when 'the latchhas to said nozzle and adapted to controltheflow of liquid therefrom, alatch adapted to engage either of the notchesin said slide, meanscontrolled by said lever; when operated to remove said latch from out ofsaid notches, means to thereupon move said hook to a position in whichthe nozzle cannot be hung thereon, and means whereby the release of saidlever causes said hook .to be locked against being'moved into apositionwhere the nozzle can be hung thereon.
